Heat EnergyHeat Energy

This energy is produced in many ways This energy is produced in many ways such as burning, rubbing, or mixing one such as burning, rubbing, or mixing one substance with another. Heat energy flows substance with another. Heat energy flows from warmer objects to cooler ones until from warmer objects to cooler ones until both reach the same temperature.both reach the same temperature.

Kinetic EnergyKinetic Energy

Energy of MotionEnergy of Motion: This is the energy of : This is the energy of an object which results from its motion.an object which results from its motion.

Electrical EnergyElectrical Energy

The energy associated with electric The energy associated with electric charges and their movements. For charges and their movements. For example, circuits provide a means of example, circuits provide a means of transferring electrical energy.transferring electrical energy.

Light EnergyLight Energy

This energyThis energy travels in a straight line until it travels in a straight line until it strikes an object. Light can be reflected by strikes an object. Light can be reflected by a mirror or lens or absorbed by an object.a mirror or lens or absorbed by an object.

Sound EnergySound Energy

This is the energy produced by This is the energy produced by making things vibrate. Sound making things vibrate. Sound energy is transferred through the air energy is transferred through the air from a source to an observer.from a source to an observer.

Potential EnergyPotential Energy

Stored energy determined by an object’s position.•An apple waiting to fall•A ball at the top of a ramp•A stretched out rubber band

Chemical EnergyChemical Energy

The energy stored in matter. Energy can The energy stored in matter. Energy can be released or consumed during a be released or consumed during a chemical reaction such as: chemical reaction such as:

Energy Can Be Transformed

Transformation = converting one form of energy to another form of energy

•An electric blanket transforms electricity to heat. Then, the blanket transfers heat to our body.

Energy Can Be Transformed

Electrical energy is transferred from the wall socket to the computer.Electrical energy is transformed to sound and light energy when the computer is turned on.Electrical energy is transformed to heat energy when the computer stays on.

Energy Can Be TransformedElectrical energy is transferred from the wall socket to the curling iron.Electrical energy is transformed to heat energy when the curling iron stays on.Heat energy is transferred to the hair that is being curled.

Energy Can Be Transformed

Light energy from the sun is transformed to chemical energy as the plants grow.Chemical energy is transformed to heat and kinetic energy as the panda eats the bamboo leaves.

Energy Can Be Transformed

The apple on the tree has potential energy due to its position.

Potential energy is transformed into kinetic energy as the apple falls and hits the man’s head.

Energy Can Be TransformedGasoline is a chemical energy. When gasoline is transferred into the car, a transformation occurs.Transformations within this system include:Heat energy Electrical energySound energyKinetic energyLight energy
